BOX HANDLE.

Application filed March 6, 1920. Serial No. 363,720.

To all whom it may concern:

Be it known that I, WALTER E. TIOLLAND,

a citizen. of the United States, residing in Philadelphia, Pennsylvania, have invented Box Handles, of which the following is a specification.

One object of my invention is to provide a simple substantial and inexpensive box handle, especially adapted for use on battery cases or trays, which shall not project beyond the end of the box and which shall be strong to resist horizontal as well as vertical strains.

Another object of the invention is to provide a novel means or device for securely fastening and holding a handle in a box end or side which shall so surround and enclose the handle ends as to protect them against corrosion by battery electrolyte, and which shall make a tight joint with the wood of the box, as well as with the handle ends, such asto prevent the entrance of liquid into the handle receiving recesses.

These objects and other advantageous ends I attain as hereinafter set forth, reference being had to accompanying drawings, in

which,

Fig. 1 is a vertical section of a part of a battery box or case, illustrating my handle and means for fastening it thereto.

Fig. 2 is a plan of the structure shown in Fig. l;

Fig. 3 is a transverse section on the line 3-3, Fig. 2; and

Fig. 4; shows an alternative construction of the undercut recess, inthe box member,

which may be made by redrilling at an angle to the first drilling or by burning with a special heated tool.'

In order to facilitate the handling of storage batteries, the wooden boxes or trays in which the cells are mounted, are usually provided with a pair of handles, mounted'to project above their ends and, in accordance with my invention, such handles are preferably made of a length of metal rod or wire bent or formed to have a flattened elliptical body 2, from which the rod ends project in parallel lines. A portion of each of these ends is preferably corrugated,

threaded or otherwise roughened or deformed so as to be more securely held by the fastening means hereafter described. Each of the ends of the box 3 to which these handles are to be applied, is preferably providedwith a pair of parallel holes extending into it from its top-edge, and these holes are preferably threaded or otherwise undercut by means of a suitable tap or cutting tool. The threads or grooves thus formed in the holes of'the wood or other material of the box are preferably relatively coarse andof steep pitch, and the upper edge of saidbo'x 3 may have a channel or recess extending between and connecting the upper ends of said holes. The holes are also preferably flared at the top.

In assembling, the ends 1 of the handle are introduced for the desired distance into the holes in the structure 3, and melted lead, alloy, or other material such as sulphur having a relatively low melting point, is poured into the recess connecting said holes, preferably at a point midway between the same. Since the holes and particularly the threads in them are of a diameter in excess of that of the rod ends 1, the molten material 4 flows freely into themfor their entire length and not only fills them, but fills also the connecting recess as indicated at 4;

Upon the solidification of. the molten material, the handleis'thus rigidly and per' manently connected tothe wood box 3, or other structure in which it is mounted, for obviously the'tubular' body ofmetal'which is cast in each of the holes not 'onlyfits-int-o the notches or grooves of the handleiend 1 therein, but also enters and conforms to the shape of the threads, or undercut recesses, of said holes. It thus forms "a relatively strong structure which is in the most intimate contact with the handle end 1, as well" as with the walls of the hole in which saidomitted from the handle ends if these ends are plated, coated or otherwise 'so prepared that the filling material 4 will bond or closely adhere to and make a rigid and practically integral connection with them; The gate or connecting portion, 4 which extends beioo v the. h irs; makes possible the filling of both recesses at one pouring and serves to tie together and brace the upper portions ofthe endsl'of the handle. If desired each of these Connecting portions may be shaped as shown at P, by means of a suitable mold, to provide a notch or recess for the reception of a hold-down hook, whereby the battery may be secured against movement.

It will be seen that the structure is particularly well adapted for use on electric batteries where it is important that the shall be strong both longitudinally andtransversely, and where the parts and fastenings shall be protected from the action of'electrolyte, which may come out of the battery cells. Also it is evident that the handle is inexpensive as well as quickand easy'to mount toruse, and thatfthe' overall battery length is not increased by the addi-- tion of the handles.

In Figb l I have shown an alternative 9Qns'truction of the undercut recesses in the box member, which may be formed by redrilling the hole originally formed, by means: of a drill operated at an angle to the line of said first hole or may be made by burning out the original hole by means of a special] heated tool. Thereafter the molten'material may be poured in the holes so formed and owing to its shape when solidified and to its adherence to or engagement with the groovesofthe handle ends, thes'e latter are rigidly held in place and entranceof liquid is; effectually prevented.
